IMPROVEMENT IN SAW-GUARDS.

Specification forming part of Letters Patent N o. 162,8 lll, dated May4, 1875; application led January 18, 1875.

To all whom it may concern:

Be it known that we, DWIGHT GRAVES and CHARLES O. HOWES, of NorthAmherst, in the county of Hampshire and State otl Massachusetts, haveinvented a new and useful Improvement in Saw-Guards, of which thefollowing is a specification The invention will iirst be fullydescribed, and then pointed out in the claim.

In the'accompanying drawing, Figure 1 is a side view ofthe guard andfoot, showing the arrangement over the saw and table. Fig. 2 is a irontview, showing a cross-section of the guard on the line x w of Fig. l.Fig. 3 is a cross-section of Fig. 1, taken on the line y y.

Similar letters ot' reference indicate corresponding parts.

A is the guard, which is preferably made of metal, but may be made ofWood or other material, with its under side made circular to correspondwith the. diameter of the saw. 1n the inner circular edge of the guardis a groove, B. This groove may be of any size, and it may receive thesaw, if desired; but ordinarily we prefer to place the guard above thesaw, as seen in the drawing. This groove receives the sawdust andprevents its iiying. The centrifugal force and motion ot' the sawcarries the dust through the groove and down through the table. Crepresents the table. D is the piece being sawed. E is the foot, whichis hinged to the stationary stand F on the guard.

The lower end of this foot is serrated and rests upon the piece l), asseen in the drawing for preventing the rising ofthe piece, and to holdit firmly in position. When this foot is not required it can be thrownback onto the guard out of the way. Attached to the guard in any manneris the piece G. This piece may be crooked or curved, as seen in Fig. 2,or made in any other suitable form. H is a slotted and groovcd piece,which is attached to the upper iioortimbers, and is ot' coursestationary. The hanging piece G lis made adjustable in the piece Hbymeans of the slot I and the bolt J, and is guided or kept in positionby the flanges K K. The pieces G and H may be made oi' either wood ormetal. Any other suitable device may be employed to render the saw-guardadjustable as to height, according to the diameter of the saw or heightof the room. L is the saw.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent, is-

The combination of slotted ange-piece H,

hanger G, guard A, stand F, and jointed foot E, all constructed andarranged to operate in the manner described.
